quantification of short- and medium-chained chlorinated paraffins (SCCP s and MCCP s, respectively) in a range of food matrices using gas chromatography-electron capture negative ionization-mass spectrometry (GC- ...

arthropods that could be found in pig farms, a better understanding of blood-feeding behaviours of stable flies and the quantification of the probability that stable flies partially fed with infectious blood ...

toxicological mode of action and dose‐response profile. This review focuses on biological, immunological, mass spectrometry, and molecular assays as the most commonly used detection and quantification methods for ...

develop a targeted analytical method utilizing liquid chromatography—tandem mass spectrometry (LC- MS / MS) for quantification of these plant toxins in a herbal-based food and human urine. The method ...

was subsequently used in an experimental setup, representing in-use conditions of MHP s, for identification and quantification of the targeted compounds. For sample clean-up, a protein precipitation ...

sensitizing fragrances in AHP ’s. This method allows simultaneous identification and quantification and was validated using the total error approach with an acceptance value of ±15%. RESULTS: The validated ...

their country, or national burden of disease studies that also use sub-national levels for burden quantifications, should consider using non-fatal burden of disease estimates to estimate geographical ...

Gas Chromatography (LC- GC) with Flame Ionization Detection (FID) is used for quantification of MOSH and MOAH. However, due to the limited availability and applications of this instrumentation, another ...

results will show the recoveries obtained for each group of FA s associated with the limit of detection for the non-authorized compounds and the limit of quantification for the FA s. Feasibility of this ...

HCH) and two brominated flame retardant congeners (BDE-47, BDE-153) were detected at concentrations above the limit of quantification in >50% of the breast milk samples. Maternal age and BMI were ...
